The VIN analysis that I purchased from Stuttcars says the engine code should be M96/0166W08070. Can I take this, along with the above date discrepancy, as confirmation of a replacement engine?

If so, what am I to make of this? I thought all engines replaced under the auspices of an official recall or Porsche-approved replacement plan are stamped with an AT in the engine code.

Any analysis from the experienced crew here is appreciated.

Lot's of problems with the early 3.4 litre engines, lots got replaced before the AT program.
